---------------------------------------------
Summary: [C++][Dataset] Integer-like partition field values outside int32 range error on reading

Small reproducer:

import pyarrow as pa
import pyarrow.parquet as pq
table = pa.table({'part': [3760212050]*10, 'col': range(10)})
pq.write_to_dataset(table, "test_int64_partition", partition_cols=['part'])
In [35]: pq.read_table("test_int64_partition/")
...
